Add a mixture of CaCO3, MgCO3 and Al2O3 weighing 0.602 g. Dissolve A in 50 ml of 0.5M HCl solution. To neutralize excess acid, 41.4 ml of 0.2M NaOH solution is required. Gaseous gas is released when A is dissolved in 93,6 ml of NaOH solution with a% concentration (d = 1,0039g / ml), then add a residue of BaCl2 solution, resulting in 0.788 g of precipitate and When boiled again, there was 0.134 more precipitate. Assuming all of these happen completely. Said
